Any help with gen_stream would be appreciated

I would like to see gen_stream get into R14B if possible. I can't
diagnose because my shell_SUITE fails every time I run it, even
standalone. Anyone out there who can reproduce the following?
1) shell_SUITE standalone passes
2) gen_stream followed by shell_SUITE causes failure
- or -
3) Using jn/gen_stream, gen_stream_SUITE fails
The last check in I sprinkled in the failing shell_SUITE command to find a
test case which triggers it, but I can't get it to fail in my environment.
tia,
